The Fallacy of Year-Round Breeding in Polyphagous Tropical Fruit Flies (Diptera: Tephritidae): Evidence for a Seasonal Reproductive Arrestment in <i>Bactrocera</i> Species by Anthony R. Clarke, Peter Leach, Penelope F. Measham

“…We subsequently demonstrate that <i>B. dorsalis</i>, across both its endemic and invasive ranges, shows a very similar seasonality although reversed in the northern hemisphere. While high variability in the timing of <i>B. dorsalis</i> population peaks is exhibited across sites, a four-month period when flies are rare in traps (Dec–Mar) is highly consistent, as is the fact that nearly all sites only have one, generally very sharp, population peak per year. …”

Exploring the potential of thermal infrared remote sensing to improve a snowpack model through an observing system simulation experiment by E. Alonso-González, S. Gascoin, S. Arioli, G. Picard

“…</p> <p>To investigate the value of TIR data to improve SWE estimation, we developed a synthetic data assimilation (DA) experiment at five snow-dominated sites covering a latitudinal gradient in the Northern Hemisphere. We generated synthetic true LST and SWE series by forcing an energy balance snowpack model with the ERA5-Land reanalysis. …”

Agerinia marandati sp. nov., a new early Eocene primate from the Iberian Peninsula, sheds new light on the evolution of the genus Agerinia by Joan Femenias-Gual, Raef Minwer-Barakat, Judit Marigó, Miquel Poyatos-Moré, Salvador Moyà-Solà

“…During the Eocene, Euprimates were mainly represented by two groups, adapiforms and omomyiforms, which reached great abundance and diversity in the Northern Hemisphere. Despite this relative abundance, the record of early Eocene primates from the European continent is still scarce and poorly known, preventing the observation of clear morphological trends in the evolution of the group and the establishment of phylogenetic relationships among different lineages. …”

Interpreting aerosol lifetimes using the GEOS-Chem model and constraints from radionuclide measurements by B. Croft, J. R. Pierce, R. V. Martin

“…Global mean aerosol lifetimes for the GEOS-Chem model are 3–6 days, which is longer than that for the ¹³⁷Cs injected at the Fukushima site (likely due to precipitation shortly after Fukushima emissions), but similar to the mean lifetime of 3.9 days for the ¹³⁷Cs emissions injected with a uniform spread through the model's Northern Hemisphere boundary layer. Simulated e-folding times were insensitive to emission parameters (altitude, location, and time), suggesting that these measurement-based e-folding times provide arobust constraint on simulated e-folding times. …”
